"We are sorry," the ads said, according to a report from Reuters. In the ads, which feature Murdoch's signature at the bottom of a letter to readers, Murdoch apologized for "serious wrongdoing" in a scandal that cost the resignation of two top editorial employees: Rebekah Brooks, the former editor of the News of the World, and Les Hinton, the head of Dow Jones—not to mention the public's trust.

Murdoch shuttered the News of the World, a storied and profitable Sunday newspaper, after allegations that the paper hacked or tried to hack into the phone lines of subjects on which the paper was reporting.
